Numbers 27:17-21

who will go out and come in before them, and lead them out and bring them in, so that the congregation of the Lord will not be like sheep that have no shepherd.”

So the Lord said to Moses, “Take Joshua the son of Nun, a man in whom is the Spirit, and lay your hand on him;

and have him stand before Eleazar the priest and before all the congregation, and commission him in their sight.

And you shall put some of your authority on him, so that all the congregation of the sons of Israel will obey him.

Moreover, he shall stand before Eleazar the priest, who shall inquire for him by the judgment of the Urim before the Lord. At his command they shall go out, and at his command they shall come in, both he and all the sons of Israel with him, all the congregation.”
